There is another utility called ldife. This one does not use csv files though. it uses a text file.
The LDAP Data Interchange Format (LDIF) is an Internet draft standard for a file format that can be used for performing batch operations on directories that conform to the LDAP standards. LDIF can be used to export and import data, allowing batch operations such as Add, Modify, and Delete to be performed in Active Directory. A utility called LDIFDE is included in the Windows 2000 operating system to support batch operations based on the LDIF standard.
Start a text editor, such as Notepad, and create a new text file named Newuser.ldf. (Save the file as an ldif file, not as a text file.)
Edit the LDIF file Newuser.ldf, and add the following text
dn: CN=JamesSmith,OU=Marketing,DC=reskit,DC=com
changetype: add
cn: James Smith
objectClass: user
samAccountName: James
> givenName: James
> sn: Smith
Save and close the LDIF file.
Run LDIFDE to import the new user into Active Directory. On the Start menu, point to Programs, then point to Accessories, and click Command Prompt. Type the following command, and then press Enter.
ldifde –i -f newuser.ldf -s hq-res-dc-01
To confirm that the new user has been created, check the Active Directory Users and Computers snap-in.
